NPS and USFS each publish their managed recreation areas through separate APIs. A scheduled job pulls both, normalizes the field names, and writes one JSON row per area keyed by slug. Areas managed jointly carry an array of agencies. The combined file feeds the page group on each cache refresh.

Ramp closures usually come through alert feeds rather than the main agency site. Carry a ramps array per area with name, current status, elevation requirement, and last-checked date. The page renders the ramps as a grid colored by status alongside the level overlay panel.

Yes through a side block. Operators publish availability through structured calendars in some cases. A second data source pulls the calendar per operator and the page renders the next available windows without re-implementing the booking flow.

Some recreation areas restrict personal watercraft to specific zones during specific seasons. Carry a pwc_rules field per area with the zone descriptions, allowed dates, and decibel limits. The page renders the rules as a structured block beside the general activity list.

Yes. Recreation areas straddle state lines in some cases and the fishing license requirements vary. Carry a fishing_licenses array per area with state, license type, and link to the issuing agency. The page renders the licenses as a list under the angler section.

Yes. Carry a stocked_species array per area with species, season, and stocking program link. The page renders the species as a grid in the fishing block. State and federal stocking programs publish quarterly reports and the data source can pull the latest events.

Lodges, marinas, and stores inside recreation areas are usually run by concessionaires under contract with the agency. Carry a concessions array per area with name, type, season, and operator link. The page renders the concessions as a directory for visitors.

Lake Chelan National Recreation Area is a unit inside a national park while its surrounding watershed is national forest. The roster handles such cases with an array of agencies and a parent_unit field that carries the larger park or forest for context.
